Gemini Omni Flash 1.1 5-second clip: 360p to 4K price

On Sume, a 5-second Gemini Omni Flash 1.1 (gemini-omni-flash-1.1) clip costs $0.1875 at 360p, $0.6250 at 720p, $0.9375 at 1080p and $1.8750 at 4K. Native synced audio is always on and included, and the model takes 3 to 10 seconds in 16:9 or 9:16.

The shape of the model comes from the Video Router docs (read 2026-10-06): 3 to 10 seconds, 360p/720p/1080p/4K, native audio that the API will not let you switch off.

What is the price per second at each resolution for 5 seconds?

Billing is per output second by resolution, at the provider list price times 1.25.

Which resolution should a draft use?

Draft at 360p or 720p and keep 1080p and 4K for the pick. The 4K clip costs 3 times the 720p one at 5 seconds, so a draft pass at 4K is the expensive way to choose between prompts.
